I think I screwed this up... I deleted a whole show that I posted and replaced it with a better mix. Now, it does not appear to be creating any derivatives. I tried to restart it in the edit menu, but no luck. Could someone help?
The derivatives only auto-generate once; if you replace files you need to manually start a new derive by going to Edit item > change the information > Item manager > derive. I gave it a kick for you this time, but just for future reference!
